We have the Bosch Rotak 32 (https://www.diy.com/departments/bosch-rotak-32-li-cordless-lithium-ion-lawnmower/1610587_BQ.prd)
Haven't had any issues and one charge should allow you to easily cut what you've showed there. We're in a new build with a small garden now, but in our old house it cut a 60m long lawn in one charge.
We have a Bosch Rotak, had a petrol lawnmower previously, believe its the Rotak 32 we have and its been great for the 2-3 years of owning it, the battery is easy to take out and charge and we can mow our lawn 2-3 times, perhaps more without needing to recharge it.
Also got a Bosch Rotak here, does the job very well. I also get about 2-3 mows per charge for a mid size back lawn, always impressed with how easy it is to mow and get the battery in and out.
